Apart from the main charging, starting and ignition circuits, there are other circuits that power lights, electric motors, the sensors and gauges of electrical instruments, heating elements, magnetically operated locks, the radio and so on. All Circuits are opened and closed either by switches or by relays - remote switches operated by electromagnets.

Also make sure you connect the “ground” wire to the “grounding” terminal of the motor. Note that this must be the power supply ground conductor, not a wire leading to a ground rod nearby.

In some circuits, there are virtual grounds, which are nodes at the same voltage as ground, but are not connected to a power supply. When current flows into the virtual ground, the voltage at the virtual ground may change relative to the real ground, and the consequences of this situation must be analyzed carefully.

If your terminal is attached by a nut to a post, use lock washers and if it is a very important connection, and most are, use blue Loctite on the post. Many electrical failures are random and due to loose connections that are hard to trace. A quick look and the connection looks good, but if it is loose, it will cause an interruption of the current flow periodically.

Some manufacturers now use printed circuits instead of bundles of wires, particularly at the rear of the instrument panel. Printed circuits are plastic sheets on which copper tracks have been "printed". Components are plugged directly into the tracks. A few modern cars have flexible printed circuits. The copper tracks are printed in ribbons of flexible plastic, which replace the whole wiring system.

There are many fuses, each protecting a small group of components, so that one blown fuse does not shut down the whole system. Many of the fuses are grouped together in a fuse box, but there may also be line fuses in the wiring.

The function of current limiting circuitry is to prevent damage to the IC when an overload is placed on the output of the regulator (the load impedance is too low). Without current limiting, the regulator would source excessive load current and destroy the pass transistor inside the part.
